Commit 4fdbfd60a3a2 ("arm64: tegra: Add PCIe slot supply information in p2972-0000 platform") added regulators for the PCIe slot on the Jetson Xavier platform. One of these regulators has an active-low enable and this commit incorrectly added an active-low specifier for the GPIO which causes the following warning to occur on boot ... WARNING KERN regulator@3 GPIO handle specifies active low - ignored The fixed-regulator binding does not use the active-low flag from the gpio specifier and purely relies of the presence of the 'enable-active-high' property to determine if it is active high or low (if this property is omitted). Fix this warning by setting the GPIO to active-high in the GPIO specifier. Finally, remove the 'enable-active-low' as this is not a valid property.
